ODIDUR V. SIGUBDSSON, OF NEW YORK, N. Y., ASSIGNOR TO ODDURMANIIFACTURING COMPANY, OF NEW YORK, N. Y., A CORPORATION OF WESTVIRGINIA.

TYPE-CASTING MACHINE.

To all whom it may concern:

Be it known that I, ODDUR V. SIcURDssoN, a subject of the King ofDenmark, residing in the borough of Brooklyn, city and State of NewYork, have invented certain new and useful Improvements in Type-CastingMachines, of which the following is a specification.

In a machine constructed in accordance with this invention the moldingdevices are controlled by means brought into action by a part movingwith the matrix disk and becoming effective to trip or start the moldingdevices only when the selected matrix has certainly reached itsoperative molding position.

A further feature of the invention is that the power by which themachine is operated maintains under constant tension spring clevices, asa spring drum, the reaction of which, when the apparatus is tripped orstarted into motion on the depression of keys in the key-board, servesto rotate the matrix-disk to bring the matrix corresponding with adepressed key to molding position.

A further feature of the invention, not dependent upon those abovementioned and capable of use in machines of any appropriate constructionadapted to its use, is that the matrices are arranged in plural seriesin or on the side of the matrix disk, the clifferent series being ofdifferent radius. By this arrangement the entire font may be disposed intwo concentric series in the side of the disk. Preferably the lower casecharacters would be in the series of greatest radius,-i. 6., thatclosest to the circumference of the disk; and the upper case charactersin the series of lesser radius. hen lower case type are cast, the diskis merely suitably revolved to bring the selected matrices intooperative relation to the mold which ordinarily and preferably would bestation ary; and when upper case characters are cast, a translation ofthe disk in a plane at right angles to its axis is effected to bring theupper case series of matrices into operative relation to the mold.

The invention further comprises certain improvements, hereinafterdescribed, in the matrix disk itself.

Specification of Letters Patent.

Application filed November 17, 1909.

Patented May 31, 1910.

Serial No. 528,477.

chines dated Dec. 21, 1909, and numbered 944,108. For this reason it hasnot been thought necessary to illustrate in detail all the parts of thetypecasting machine.

The accompanying drawings show certain organizations serving for theoperation or control of the typematrix disk and mold from the key-boardof the machine; and practical experience has shown that theseconstructions are suitable and well adapted to their intended purposesbut they may be varied by those skilled in the art without departingfrom the principles of this invention.

Figure 1 is a perspective view showing a matrix disk, its driving springdrum, matrix-selecting devices and means whereby the positioning of theselected matrix is caused to initiate the operation of the moldingdevices. Fig. 1 is a similar view. showing the stop devices indicated inFig. land a way of controlling them from the keyboard. Fig. 2 is asimilar view showing means by which, when a key in the board isdepressed, the matrix disk is released or tripped and may, therefore, berotated to the desired extent to bring the corresponding matrix to themolding point. Fig. 2 'is a detail elevation showing a means of movingthe matrix disk at right angles to its axis. Fig. 2 is a detailelevation of part of Fig. 2. Fig. 2 is a plan view of Fig. 2 Fig. 2 is asection on line A, B, of Figs. 2 and 2. Fig. 3 is an elevation of thematrix face of a matrix disk. Fig. 4: is a partial elevation of theopposite or rear face thereof. Fig. 5 is a central cross-section. Figs.6, 7 and 8, respectively, are views corresponding respectively to Figs.3, 4 and 5 but showing a disk having plural and concentric series ofmatrices.

The matrix disk will first be described by referring to Figs. 3, 4 and 5:It has a central bearing aperture 1, preferably surrounded by athickened or hub portion 2. There is set into its matrix face, or frontface as it will be called, a series of matrices 3 arranged concentric tothe axis of the disk. It has not been thought necessary to show in thedrawing the entire series. It is, of course, immaterial so far as thisinvention is concerned, how the matrices are formed or let into thesurface of the disk. On the opposite or back face of the disk oppositethe matrices respectively, the disk is milled to produce radial groove-s4 formed by ribs 5; and, opposite the end of each such groove, is atapped recess (3. In the peripheral face of the disk is an annulargroove 7. Opposite each matrix and fitted in the radial groove 4 is ahard metal piece 8 having a flange with a lip 9 that fits in the annulargroove 7 and an aperture through which a screw 10 passes into thethreaded recess 6. The piece 8, immediately back of or opposite thematrix, is formed with a raised face 11 in which is an aperture 12. heaperture 12 is for the reception of a locking-pin; and the raised face11 forms a bearing for the shoulder on the pin that determines the widthof the mold to correspond with the particular matrix. The elevations ofthe several surfaces 11 correspond with the widths of the type to becast. This means of locking the disk with the selected matrix at themolding point, of pressing the matrix against the face of the mold andof determining the adjustment of the mold with respect to the width ofthe character to be cast may all be precisely the same as disclosed inmy Letters Patent numbered 94%,108 before mentioned. This constructionof matrix disk permits of the ready removal and accurate replacement ofthe parts 8, in the event of their becoming worn, injured or distorted.

Figs. 6, 7 and 8, show a matrix disk in all. respects the same as thatalready described except that there are two concentric series ofmatrices, 3, 3*, and there are therefore on the rear face of the matrixdisk two corresponding concentric series of raised surfaces, 11, 11,each having its recesses 12 for the locking-pin.

If the normal position of the matrix disk is such that the matrices ofthe outer series 3 are in proper relation to the mold, :then it isnecessary either that the mold be moved radially with reference to thedisk to bring it into proper relation with the inner series 3 of thematrices, or, that thedisk be moved in a plane at right angles to itsaxis. Either mode of operation may be adopted but the latter ispreferred because of its greater simplicity. For convenience ofdescription the matrix disk will be designated as 13.

leferring now to Fig. 1, matrix disk 13 is fast on a shaft 14- adaptedto be rotated by an ordinary spring drum 15 maintained constantly woundby a cord belt 10 driven by the constantly acting motive power by whichthe operations of the machine are carried out under control of thekey-board. l-n shaft 1t is secured a radial arm or block 17 having in ita slot 18 transverse to the axis ll. In this slot is pivoted a latch 19having a tail piece 20 to which is applied a coiled reaction spring 21the end of which is secured to the hub or bearing portion of the block17. In order that the matrix corre' spending with the depressed key inthe keyboard shall be arrested at the proper point with respect to themold, there is provided a circular series of movable stops 22 shown indetail in Fig. 1 and hereinafter described. These stops may be mountedto slide endwise in a fixed cylinder or drum concentric to the shaft14-. There is one such series of stops for both series of matrices; thatis to say, if the disk be such as shown in Fig. 1, there will be a stopfor each matrix; if the disk be such as shown in Fig. 6 there will be astop for each matrix of the outer series; and, since the matrices of thetwo series are arrai'lged in radial lines, one series of stops willserve for both series of matrices. Operative connections, such asbell-crank levers, links, rods and slides, extend from the respectivestops or slides 22 to the key-board and are there controlled so that onthe depression of a key its corresponding stop 22 will be moved into thepath of block 18 fast on the matrix disk shaft, and therefore the matrixdisk will be arrested by abutment of block 18 against stop 22 at theproper point to position the selected matrix at, or opposite, themolding point. In Fig. 1 neither the entire series of steps 22 nor theentire series of matrices is shown. hen the molding operation iscompleted, the stop is withdrawn by the controlling cam or otherpower-actuated device and all the parts return tonormal position ashereinafter described. As block 18 approaches stop 22, the curved faceof latch 19 rides under the stop and the leading end of the latch isforced down, thereby causing its rear end or tail 20 to draw up a link23 that carries upon its end a cam face 21 which, as the link movesupwardly, cams outwardly a ring encircling shaft 11 and having anextension 26 fast 011 a rockshaft 27 that also-carries a radial arm 28to which is pinned a link extending downward to a bell-crank latch 30pivoted at 31 upon a fixed part of the machine. This latch 30 normallyholds up a lever-arm 32 to which is applied a coiled spring 33 whosereaction tends to draw down the arm. The arm 32 fast on a rock-shaft 34-having secured to it a radial arm 35 to which is pinned a link 36 thatacts to trip or set into operation the molding devices. The moldingdevices may be operated and controlled as in my Letters Patent No.944,108 above mentioned, or in any appropriate or suitable manner. Theparts are so related that the movement of latch 19 effects the trippingand starting of the molding devices at, or a moment before, the selectedmatrix is in position but casting can never occur until the matrix hasreached the molding position because the parts are so timed that thetripping or starting of the molding devices by arm 36 cannot occurbefore the selected matrix is closed against the mold.

Fig. 2 shows a manner in which the matrix disk may be tripped orreleased on depression of a finger-piece or key in the keyboard. Thematrix disk shaft 14, or rather that part of it appearing in Fig. 2, isa prolongation beyond the ring 25 shown in Fig. 1. Keyed on this shaftis a snail or eccentric piece 37 having a shoulder 38 normally engagedby a two-armed stop-pawl 39 embracing the snail piece and pivoted at 40;coiled spring 41 has one end applied to that arm of the pawl thatengages the shoulder 38, and the other end is attached to a fixed pointon the frame. Below the pivot 40, the pawl has a circular hub or arm 42that is bored out and has seated in it a coiled spring 43 that tends toforce outwardly a circular block 44 fitting in the hub. This block hasformed on its end face a shoulder 45 that is normally engaged by a fixedpiece or plate 46. Bearing upon the face of the block 44 is an arm 47fast on a rock-shaft 48 having fast on it another radial arm 49. Looselyturning on the rock-shaft is a link 50 to the end of which is pinned apendent link 51 pivoted at its lower end to an arm 52 fast on a shortrock-shaft 53 having also fast upon it an arm 54 to the. end of which issecured a cross-bar 55. 56 is a plate form ing part of the key-boardstructure and having in it a series of slots. In these slots are fitted,to slide vertically, plates 57 each having a shoulder 58 underlying thecross-bar The key-levers (one only being shown) may be mounted to rockabout the axis 60 intermediate its ends. Its front end is equipped withthe usual finger-piece 61 and its rear end engages a notch 62 in uprightplate 57 of which latter there is one for each key-lever. lVhen thefinger-piece 61 is depressed plate 57 is drawn upwardly raisingcross-bar 55 and causing link 51 to move upwardly thereby raisinglever-arm 50. Secured to lever-arm 50 is a vertical post 63 in the endof which is pivoted a latch 64 having a block or shoulder 65 thatengages the end of the radial plate or arm 49 on rockshaft 48. The freeend of latch 64 rides upon the fixed upwardly inclined cam face 66.When, therefore, link 51 is forced upwardly, the shoulder or block .65on latch 64 forces arm 49 rearwardly and elevates arm 47 which pushesupwardly, against the tension of spring 43, the latch plug or block 44so as to disengage it from the fixed stop-plate 46 at which time thereaction of spring 41 will throw stop-pawl 39 out of engagement with theshoulder of snail 37, thereby releasing the matrix disk shaft andpermitting its rotation by the spring drum. The shoulder 38 of the snailwill, as the shaft rotates, cam outwardly the other arm of the stop-pawland restore the parts to normal position so that when one revolution ofthe shaft has been completed the shaft will be arrested, and all theparts will again have assumed the position indicated in Fig. 2.

Fig. 1 shows a means of operating the stops 22. It should be understood,however, that any suitable means may be used, that illustrated beingmerely one of many ways that may readily be devised by skilledmechanicians. The upper portions of plates 57 are angularly disposed inthe planes of their flat sides as'at 67 and work in slots 68 in a fixedcross-plate 69. When the plates are elevated by depression of theircorresponding key levers 59, their extreme upper ends cam out radialarms 7 0 each of which is fast on a rock shaft 71 that carries anotherarm 72 forked at its end to embrace a pin 22 on its correspondingsliding stop 22. When, therefore, a key lever is depressed, the matrixdisk 13 is set in motion and the corresponding stop 22 advanced into thepath of latch 19 and block 17. The stops, of which there should be onefor each key lever, are arranged in a circle but do not occupy theentire circle since there should be a space as indicated at 73 wherethere are no stops and opposite which the block 17 stands when the partsare in normal position of rest.

To effect translation of the disk at right angles to its axis when amatrix disk with plural series of matrices is used, the generalconstruction disclosed in my said Letters Patent numbered 944,108 may beadopted.

This construction is shown in Figs. 2 to 2 One section 14 of shaft 14has fast on its end (Figs. 2 and 2 a circular head 74 with a deepdiametric slot 75 in which works a square bar 76 having its lower endpivoted at 77 in a plate 78 secured to one end of the intermediate shaft14 to the other end of which is keyed the matrix disk 13. The othersection 14 of shaft 14 has on its end contiguous to the matrix disk ahead 79 having in it adeepradial slot 80 in which Works a square bar 81pivoted at 82 to the side of the matrix disk on an axis in line with theaxis of pivot 77. Hence the intermediate section 14 of the shaft isrotated coincidently with rotation of shaft 14 by the spring drum 15, orother motive power, and yet shaft section 1s may be moved (ashereinafter described) transversely to its axis to bring a selectedmatrix on disk 13 properly opposite the orifice or mouth of a type mold83. The conical socket 8-1 of the mold for the reception of the nipplethrough which molten metal is injected into the mold cavity is indicatedby dotted lines in Figs. 2 and 2 A matrix on the sideof the disk 13having been selected when the disk is in either normal or translatedposition, the shaft section 14 is moved endwise to the right (as viewedin Figs. 2 and 2) to close the matrix against the mouth of the mold. Thedrawing show", fast on shaft section leta hub or sleeve 85 having at itsends flanges 80 between which disposed a shaft shifting yoke 87, thelever arm 88 of which may, at the proper time, be operated upon by anyappropriate means, as a cam, to shift the shaft section and close thematrix against the mold. The drawing shows the shaft section 1 1 asturning in bearings in the ends of a pair of pa 'allel arms 89, 89,passing through slots 90 in a fixed frame piece 91 and pivoted upon acommon axis 92 at their other ends. Intermediate the axis 92 and framepiece 91, the arms have coincident transverse apertures 93 in which acam bar 94 works. This cam bar is guided in apertures in fixed frameplates 95 and has jointed to one end an arm 96 fast on a rock shaft 97having another arm 98 disposed at about right angles to arm 90, theconstruction being, in effect, a bellcrank lever. To arm 98 is jointed alink 99 pivoted at its lower end (Figs. 2 and 2 to the rear end of ashift key lever 100, pivoted intermediate its ends at 101, havingpivoted to its front end a finger piece push pin 102 notched at 103 toengage a locking piece 101 and into engagement with which a spring 105normally tends to urge it. hen the finger piece 100 is depressed the cambar 9% is moved endwise to effect translation of the matrix disk intothe position in which type may be cast from the inner series of matriceslocated in its side. The latch 103, 10-1, will retain the parts in suchposition as long as desired and may be released by lateral pressure onthe fingerpiece. Suitable reaction springs will of course be usedwherever needed. One such spring 107 is shown applied to the shift keylever and it alone may be of adequate strength to return the cam bar andassociated parts to normal position when pressure on the finger-piececeases or its latch is released.
